We study localization of bosonic bulk fields on a stringlike defect with codimension 2 in a general space-time dimension in detail. We show that in cases of spin-0 scalar and spin-1 vector fields there are an infinite number of massless Kaluza-Klein states which are degenerate with respect to the radial quantum number, but only the massless zero-mode state among them is coupled to the fermion on the stringlike defect. We also comment on interesting extensions of the model at hand to various directions such as ``little'' superstring theory, conformal field theory, and a supersymmetric construction.
